Operations generating greasy wastewater have a mandatory obligation to install EN 1825 type grease separators to ensure that grease and organic oil is effectively removed from the wastewater. This applies for instance to kitchens and meat-processing operations. It is mandatory for every grease separator installed below the backflow level (usually corresponding to street level) to have a downstream twin lifting plant or complete pumping station. Each industry and commercial operation places individual demands on the capacity of grease separators, lifting plant and complete piping stations. Customisation therefore requires adaptable products in a wide range of sizes and materials. ACO Building Services has many decades of experience in supplying the most diverse range of grease separators, lifting plants and complete pumping stations for ground installation and free-standing installation. Die Normen und Prüfungen All ACO Building Services grease separators are manufactured in accordance with EN 1825 standard. All of the grease separators in the product line are hydraulically tested and have General Building Supervisory Authority Authorisation and/or the new Application Authorisation from DIBt Berlin. The separators also undergo regular inspection by the Bavarian Factory Inspectorate which inspects the grease separator production to ensure it complies with the latest testing standards.

If the resting water level lies below the backflow level (generally corresponding to street level), there is a mandatory obligation to install active backflow safety valves (Lifting plant or pumping station). 2. Caution: ground : installation: To avoid additional costs and unnecessary co-ordination work, we recommend which comply with the specified structural load without additional reinforcing (e.g. load distribution slabs) for example Oleomax, Oleopator and Eco-FPI. 3. Caution: free-standing installation of grease separators: We recommend installing stainless steel separators when the operational temperatures in the separator > 60 C or when the separator is installed in a fire-risk zone.

4 Grease separators for full disposal Full disposal A grease separator for full disposal operates purely physically on the basis of gravity (density differences), i.e. heavy wastewater constituents sink to the floor of the separator, light substances such as animal fats and oils, rise to the top of the grease separator. The treated wastewater is discharged into the sewers via a drainage outlet pipe.... for free-standing installation The sludge trap and the separator must be completely emptied and cleaned at least once a month pursuant to DIN Emptying the sludge trap and the separator is carried out by a disposal company and it is recommended that this operation be carried out every two weeks. The separator then has to be refilled with water (e.g. drinking water or process water) in compliance with the local water regulations. Extension stages All gravity grease separators require periodic maintenance to remove the fats, oils and grease (FOGs) together with sludge deposits. Such maintenance is usually undertaken by a specialist waste contractor. A system of extension stages for grease separators enables the reduction of odor during disposal and cleaning. The higher the extension stage, the more comfortable disposal and cleaning of the separator can be accomplished. The available extension stages and the respective comfort for disposal and cleaning are described in the table below. 4 Basic version Extension stage 1 Extension stage 2 Extension stage 3 Dipsosal via inspection covers With connection for direct suction With connection for direct suction With internal high pressure cleaning (manual operation) With filling device (manual) Disposal pump (option) With connection for direct suction With internal high pressure cleaning (automated operation) With filling device (automated) Disposal pump (option) Occurrence of odour during disposal and cleaning Disposal can be done without opening of the covers.

6 Materials and models POLYETHYLENE Very durable Polyethylene has excellent corrosion-resistance properties Recycling Polyethylene is environmentallyfriendly and reusable! Maintenance Cleaning is simple thanks to the smooth wax-like surface. Transport Low weight for easy transport and installation! STAINLESS STEEL Fire protection Stainless steel is completely inflammable and therefore presents zero fire-risk. It is also very temperature-resistant. Strength Stainless steel has very high levels of mechanical strength and is therefore vandal-proof. Hygiene Stainless steel has been used for many decades in all applications specifying strict hygiene regulations (e.g. hospitals). Chemical resistance Stainless steel is extremely resistant to organic substances. 6 OVAL MODEL The container dimensions of the oval grease separators made of polyethylene and stainless steel have been optimised to maximise ease of access in awkward situations. This means they can be easily carried into areas via narrow stairs and door openings. NS 1-4: max. width 800 mm -10: max. width 1050 mm ROUND MODELS The round grease separator models made of stainless steel or polyethylene can be dismantled into separate components. This design also means that the nominal size can be enlarged on site by simply replacing the middle components (e.g. replacing NS 7 with NS 10). Number of separate components: -4: 2 components; Ø 1000 mm NS 7-10: 3 components; Ø 1500 mm NS 15-20: 3 components; Ø 1750 mm SPLIT DESIGN This product line is made of polyethylene and is specially designed for remediation projects with very narrow access routes. The separator can be split into three parts. Maximum segment dimensions (LxWxH): NS2 : 670 x 700 x 1360 mm NS4 : 1140 x 700 x 1360 mm

7 Grease separators for partial disposal Grease separators for partial disposal (Fresh grease separators) Grease separators working on the partial disposal principle also operate purely physically on the basis of gravity (density differences), i.e. heavy wastewater con-stituents sink to the floor of the separator, whilst light substances such as animal oils and fats rise to the top of the separator. The separated substances (grease and sludge) are collected in separate containers. The treated wastewater is then discharged into the sewers via the drainage outlet pipe. Partial disposal (Fresh grease disposal) Draining the separated substances from the grease separator into the collecting drums is done by opening the relevant drainage valve on the separator (specifics depend on the type of operation). This can be undertaken independently of normal operations. For example, it can be done without interrupting the work being carried out in a kitchen. Because the collecting drums only take up grease and sludge, the grease separator does not have to be filled after disposal with expensive fresh water. Lipator: Grease separator for partial disposal with manual operation. Lipatomat: Grease separator for partial disposal with automatic program control. Partial disposal concept ACO Building Services provides two types of grease separator for partial disposal: grease separators for manual, or automatic partial disposal. Both of these versions are only available for free-standing installation. The grease separators for manual partial disposal (LIPATOR) have mechanical drainage valves. These must be opened several times a day as required by the operator (after heating up first). The transparent hoses reveal whether all of the substances collected at any given time have completely drained into the drums. The grease separators with automatic partial disposal (LIPATOMAT) have electrically actuated ball valves. A programme control automatically activates the pre-heating and opens the valves. An optical and acoustic warning signal is activated when the collecting drums are full. Full drums are simply replaced and collected by a disposal company. 7

32 Special solutions: upstream tank system with eccentric spiral pumps 32 Application example: when inlet pipe connections to grease separator systems are positioned too low Low inlet pipe heights always cause problems when there is no gradient between the inlet piping and the grease separator. If it is not possible to undertake construction measures to lower the height of the grease separator, the only alternative is to pump the wastewater up to the grease separator. This is not possible using conventional lifting plant because of the grease in the wastewater. Normal lifting plant would also cause turbulence in the grease separator and disrupt the separation process. The solution is to install a displacement pump (e.g. eccentric spiral pump). The ACO eccentric spiral pumps are connected to an upstream tank (made either of polyethylene or stainless steel, or a concrete shaft built on site). The inflowing wastewater collects in this tank. If the inlet pipe lies in the concrete floor slab (as in the diagram above), a shaft has to be built on site to house the tank. A pneumatic pressure switch installed in the buffer tank is activated when the wastewater reaches a pre-set level and switches on the eccentric spiral pump. Spiral pumps cannot become blocked up with grease. The wastewater is then pushed into the grease separator without turbulence. All eccentric spiral pump installations are customised for each project. Please contact our sales consultants in our office or our field sales staff.

33 Special solutions: secondary treatment of greasy wastewater Application example: optimising the efficiency of grease separators Grease separators usually only separate out freely separatable oils/grease and solids. Emulsified and dissolved constituents in the wastewater largely pass right through the separator. This almost automatically means exceeding the limits when stringent regulations are laid down for lipophilic substances. Because many local authorities are taking an increasingly strict view of lipophilic substances, it is often necessary to install additional treatment steps downstream of grease separators. The ideal solution is the ACO Biojet biological wastewater treatment system. This is a particularly environmentallyfriendly solution specially designed by ACO Building Services for this purpose. This proven technology permanently and reliably keeps levels of low volatile lipophilic substances below statutory limits. It also effectively reduces COD and BOD5 levels, ph, and the volumes of settling solids. Our ACO Biojet brochure explains and describes in detail the functions, areas of application and product solutions for this technology. Please contact our technical experts, either in our office or our field sales staff, if you have any questions. 33
